Greta Schultz (Lolita Sahwany) is the secondary antagonist of the 2004 animated short "Rex Steele, Nazi Smasher".
When hero Rex Steele is sent on a mission to an Amazon City that has been transformed into a Nazi base, he becomes incapacitated via blow darts by Greta's henchmen. The villainess has him tied down beneath a giant drill which the Nazi leader, Schnitzler, plans to use on a volcano in order to create a secret missile silo. However, Rex's sidekick, Miss Penny Thimble, manages to show up in the nick of time to free him. Rex then fends off the Nazi goons while Penny engages in a catfight with Greta. In the end, the heroes prove victorious and Greta is captured.
